Phenolic compounds from <i>Limonium densiflorum</i> : a multifaceted approach to antioxidant, anti-inflammatory, anticancer, and anti-influenza activities
Bibliographic record
Abstract
Exploration of the hydroethanolic extracts from the halophyte Limonium densiflorum, led to the isolation of seven phenolic compounds: gallic acid, epigallocatechin gallate (EGCG), quercitrin, a mixture of myricetin 3-O-α-rhamnopyranoside + myricetin 3-O-L-arabinofuranoside, dihydrokaempferol, pinoresinol, and trans-N-ferulolyl tyramine. These compounds were assessed for anticancer, anti-influenza A virus, antioxidant, and anti-inflammatory properties. The results indicated that these compounds do not exhibit toxicity towards healthy cells (WS-1 and MDCK). Furthermore, they displayed strong antioxidant properties. Among these compounds, gallic acid, the mixture of myricetin 3-O-α-rhamnopyranoside + myricetin 3-O-L-arabinofuranoside, dihydrokaempferol, and pinoresinol, showed significant cytotoxicity against colon cancer cells (IC50: 1-39 µg/mL). EGCG, gallic acid, dihydrokaempferol, pinoresinol, and trans-N-ferulolyl tyramine demonstrated potent anti-inflammatory activity by reducing nitric oxide (NO) production and also inhibited the replication of the influenza A virus. Biological activities varied based on compound structure, with phenolic acids and flavonoid aglycones showing stronger effects than glycosylated compounds and lignans.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
